The geometry of domains with negatively pinched K\"ahler metrics

, 2018
We study how the existence of a negatively pinched K\"ahler metric on a domain in complex Euclidean space restricts the geometry of its boundary. In particular, we show that if a convex domain admits a complete K\"ahler metric, with pinched negative ...

Kähler tubes of constant radial holomorphic sectional curvature

Manuscripta Mathematica, 1997
Let \(\pi: N\to P\) be a \(C^\infty\) complex vector bundle of real rank \(2k\) over a Kähler manifold \(P\) and let \(M^k(4\lambda)\) be a complex space form of constant holomorphic sectional curvature \(4\lambda\) and complex dimension \(k\). Using these data, the authors have introduced in [\textit{A. Lluch} and \textit{V. Miquel}, Geom. Dedicata 61,

Hermitian manifolds with semi-positive holomorphic sectional curvature [PDF]

Mathematical Research Letters, 2016
We prove that a compact Hermitian manifold with semi-positive but not identically zero holomorphic sectional curvature has Kodaira dimension $-\infty$. As applications, we show that Kodaira surfaces and hyperelliptic surfaces can not admit Hermitian metrics with semi-positive holomorphic sectional curvature although they have nef tangent bundles.

Nonnegative Holomorphic Sectional Curvature on Compact Almost Hermitian Manifolds

Taiwanese Journal of Mathematics
Summary: We study nonnegative holomorphic sectional curvature on a compact almost Hermitian manifold. In the positive case, we show some geometric conditions for negative Kodaira dimension. In the zero case, we give some conditions of the Chern-Yamabe problem for zero Chern scalar curvature.
